sdt22, Incidence is the angle of the wing measured off the fuselage datum line. I think you will find your problem to be decalage, this is the relationship between the wing and the tail, and the problem could be at either end. Also if memory serves me the H9 recommended balance points for the Aresti are from 26%-29% MAC, this is very conservative and most fly them at around 32%
